My mother in law got 6 buff Orpington chicks that are around 8-10 weeks old a couple of weeks ago. Some of them have a clear nose drainage, occasionally sneeze and I can hear a tiny noise when they breath. She said they are eating, drinking and very active and symptoms don't seem to be getting any worse. I have read about Coryza having a smell associated with it and I am not sure what that smell is like but these babies stink! If it's Coryza would they be getting worse instead of staying the same? Any advise I can give her would be great. They are very sweet chickens and like to jump up in her lap so she is pretty attached already.
